Question

Lichens are a mix of two organisms—a fungus and an alga. The alga, by virtue of its ability to carry out photosynthesis, provides food for the fungus. The fungus, in turn, protects the alga by forming a covering over it. What kind of an interaction is being exhibited by the fungus and the alga?

Answer 1

Mutualism

Explanation:
